Height-adjustable bed

Abstract

A bed, in particular a sickbed or nursing bed, comprises a height-adjustable bedstead having a frame comprising frame side parts and frame transverse parts and, in the region of the frame transverse parts, legs connected with each other in pairs by means of cross bracings. The legs have lower ends supported on a floor and, at their opposite upper ends, are supported and slidably guided at guiding profiles extending in parallel to the frame side parts. Further, the bed comprises two lifting assemblies each having a drive unit comprising a housing, and a pushrod adapted to be moved out of the housing and into the housing by the drive unit. The two lifting assemblies are arranged in the region of the frame side parts, leaving a space for accommodation of an adjustment drive for an adjustable mattress supporting device.

1. A bed, in particular a sickbed or nursing bed, comprising:
 a height-adjustable bedstead having a frame comprising frame side parts and frame transverse parts and, in the region of the frame transverse parts, legs connected with each other in pairs by means of cross bracings, wherein the legs have lower ends supported on a floor and, at their opposite upper ends, are supported and slidably guided at guiding profiles extending in parallel to the frame side parts, and 
 two lifting assemblies each having a drive unit comprising a housing, and a pushrod adapted to be moved out of the housing and into the housing by the drive unit, 
 wherein each lifting assembly extends between one of the frame transverse parts and the cross bracing arranged between the pair of legs opposite the frame transverse part, and wherein at the housing as well as at a free end of the push rod facing away from the housing, each lifting assembly is connected with the respective frame transverse part or the cross bracing, and, 
 wherein the two lifting assemblies are arranged in the region of the frame side parts, leaving a space between the two lifting assemblies for accommodation of an adjustment drive for an adjustable mattress supporting device. 
 
   
   
     2. The bed according to  claim 1 , wherein each cross bracing comprises a cross brace and two angular or arcuate braces which extend from the cross brace to the upper ends of the legs, and, at the angular or arcuate braces, the legs are guided and supported at the guiding profiles. 
   
   
     3. The bed according to  claim 2 , wherein the legs are articulated to support braces which are supported at the frame in a manner rotatable about axes extending in parallel to the frame transverse parts. 
   
   
     4. The bed according to  claim 1 , wherein the legs are articulated to support braces which are supported at the frame in a manner rotatable about axes extending in parallel to the frame transverse parts.
